Plant nutrients are dissolved in the water used in hydroponics and are mostly in inorganic and ionic form. Primary among the dissolved cations (positively-charged ions) are Ca2+ (calcium), Mg2+ (magnesium), and K+ (potassium); the major nutrient anions in nutrient solutions are NO3- (nitrate), SO42- (sulfate), and H2PO4- (phosphate).

All plants require the right nutrients to help them grow strong and stay healthy. Bestes Hydroponics stocks a vast variety of nutrient solutions for your hydroponic garden.
